Q1: What are the benefits of installing a DPF/EGR delete and CCV catch can on my 6.7L Powerstroke?
A1: Removing the DPF/EGR reduces exhaust restrictions, improving fuel economy (1-3 MPG gain), throttle response, and turbo longevity. The CCV catch can prevents oil vapors from entering the intake, reducing carbon buildup and protecting your engine.
Q2: Will deleting my DPF/EGR cause check engine lights or tuning issues?
A2: Yes—a proper ECU tune is required to disable emissions-related sensors and prevent error codes. Off-the-shelf or custom tuning ensures smooth operation.
Q3: Is a catch can necessary if I’ve already deleted my EGR?
A3: Yes! The EGR delete stops soot recirculation, but the CCV system still releases oil vapors that can clog your intercooler and intake. A catch can solves this.
Q4: How often do I need to empty the catch can?
A4: Depending on driving conditions, every 1,000–3,000 miles. Towing or heavy use may require more frequent servicing.
Q5: Will these modifications pass emissions testing?
A5: No. DPF/EGR deletes are illegal for on-road use in most regions. These upgrades are recommended for off-road/track vehicles only.
